Gian Maria Visconti

Gian Maria Visconti (7 September 1388-16 May 1412) was the Duke of Milan from 1402 to 1412, succeeding Gian Galeazzo Visconti and preceding Filippo Maria Visconti.

Biography
Gian Maria Visconti was the eldest son of Gian Galeazzo Visconti and Caterina Visconti, the rulers of Milan. However, he inherited a disintegrating duchy that soon fell into the hands of many rulers such as the condotierro Facino Cane. Cane convinced Visconti that his mother was turning against him, so Visconti had her murdered in prison. Gian Maria became famous for his use of dogs to slaughter men, which disgusted the Ghibellines of Milan, who arranged for him to be assassinated. He was stabbed to death in front of San Gottardo in Milan.
